He is not willing to accept the case because the client refuses to testify.
I have tranformed the sentence as follows and wonder if it is correct. The given word is 'His'.
What causes me to doubt is the phrase 'the client', but my transformed sentence starts with His client.
His client refuses to testify, so he is not willing to accept the case.
In the original sentence, it is not explicitly stated that the client is his. Common sense tells us that the client must be his client, but common sense is rarely a factor in test questions. All we can say on the evidence we have is something like: His unwillingness to accept the case stems from the client's refusal to testify'.
